JPH0633094B2 - A bag with a closed articulator - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a bag body provided with a male and female claw type openable and closable device having a closed structure at the opening of a synthetic resin bag body. .

[Conventional technology]

In the conventional bag with the synthetic resin bite, the male and female nail type bites 3 having various shapes as shown in FIGS. 4 and 5 are provided.
The bag 1 is provided in the opening 2 of the bag 1.

However, all of them are intended for storing and taking in and out of solid products, and therefore the structure of the articulation tool 3 is focused on holding the stored product and smoothly opening and closing the articulation tool 3 for taking out the product. However, there was no structure for the function of preventing ventilation for maintaining the quality of the contents or preventing water leakage of water products, or even if such a structure was made, it was not practical. .

[Problems to be solved by the invention]

In the above-mentioned conventional general clasp with an engaging device, since the male claw 4 is fitted into the female claw 5, the fitting space portion is larger than the cross-sectional size of the male claw 4. Therefore, a gap O exists in the inner wall of the female claw 5 after the male claw 4 and the female claw 5 are occluded. Therefore, the male nail 4 after occlusion
Cannot maintain close contact with the female nail 5, and the female nail 5
Since it floats in the space of the device, the venting device 3 can freely vent or leak water. Therefore, if foods such as coffee, tea, seaweed, etc. that require airtight preservation and spices, and pickles that require water retention are stored in the bag, the quality will change due to aeration and water flow. It has been unsuitable to store various kinds of products in a conventional bag with an articulator.

SUMMARY OF THE INVENTION The present invention provides a bag body with a synthetic resin engaging device that has a reliable sealing function to solve the above-mentioned conventional problems, and that also has a reopening and closing function.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, the present invention provides an openable male / female nail type bag with an articulating device in which two parallel clamping valves 6 are provided at the base portion of the female nail 5. is there. The length L of the pinching valve 6 is longer than the distance l between the tip of the male pawl 4 and the base of the female pawl 5 in the space C formed when the male and female pawls 5, 4 are engaged. Furthermore, the parallel clamping valves 6,
The interval u of 6 is set to be smaller than the maximum width v of the male claw 4, to be wider than the cross-sectional width of the male nail tip portion, and to allow the tip portion N to be sandwiched on both sides thereof.

[Action]

Since the female claw 5 and the male claw 4 of the present invention are configured as described above, when a force for engaging the male and female bite is applied by a fingertip or the like, as shown in FIG. Male claw tip N
Is inserted into the pinching valve 6 on the female pawl 5, and the pinching valve 6 is pushed to the left and right. For this reason, the space portion O that allows the male and female nails 5, 4 to occlude can be occluded.

As described above, when the occlusal pressure of the male and female claws 5 and 4 is completed (Fig. 3), the two pinching valves 6 and 6 that have been spread when the occlusal pressure by the fingertip from the outside is released. The elastic force of the sandwiching valves 6, 6 starts to return to the parallel state of the base, so that the male pawl 4 is pushed upward by the elastic repulsion of the sandwiching valves 6, 6.

As a result, the female claw 5 and the male claw 4 are separated from each other by the tip hook portion a of the male claw.
At the tip claw b of the female claw, the tip claw a ′ of the male claw, and the tip claw b ′ of the female claw, the force of the clamping valves 6 and 6 to restore the original shape and the female claw 5 keeps the original shape. Since the forces applied are in a folded state and come into close contact with each other, it is possible to maintain the closed state of the articulation tool.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 5, 1 is a bag body, 2 is an opening portion of the bag body, and 3 is a male and female contact type occlusion device which is provided in the opening portion of the bag body and which can be freely opened and closed. As shown in FIG. 1, two clamping valves 6 and 6 made of synthetic resin having elasticity as described above are provided in parallel with each other on the base bottom surface of the female claw 5 in the engaging device 3. The interval U between the sandwiching valves 6 and 6 is set to be smaller than the maximum width v of the male pawl 4 but wider than the sectional width of the male pawl tip. Then, as shown in FIG. 2, the tip end portion N of the male pawl 4 is inserted between the sandwiching valves 6 and 6 so as to push the sandwiching valves 6 and 6 to the left and right.

The length L of the holding valves 6 and 6 is larger than the distance l between the tip of the male pawl 4 and the base of the female pawl 5 in the space C formed when the male and female pawls 5 and 4 are engaged. .

[Effects of the Invention] In the bag provided with the clasp according to the present invention, the bag with the conventional clasp was not suitable for storage, articles requiring more airtightness, aromatic foods, Alternatively, it has become possible to apply the bag with the clasp to the packaging of a wide variety of articles of various types, including the application to foods that require moisture.

In the conventional bag with an articulating device, in order to prevent ventilation and water leakage as much as possible, it was necessary to make the space O of the male and female claws 5 and 4 as narrow as possible, but this point is not neglected. It was tied to the difficulty of fitting. In the bag with an engaging device according to the present invention, the existence of the sandwiching valves 6 and 6 having elastic force ensures the space O necessary for fitting without any loss of the sealing property. Therefore, it is possible to perform a smooth opening / closing operation as in the case of a general bag with an engaging device.
